Whakarāpopototanga: E whakaahua ana tēnei tuhinga i ngā painga me ngā ngoikoretanga o ngā pūnaha whakahaere kume o te whakatuwheratanga mowhiti me te porowhita kati i roto i ngā mīhini whakakikorua kore-whakarewa. Hei whakamutunga, he pai ake te mahi a te pūnaha whakahaere kume porowhita kati i te pūnaha whakahaere kume whakatuwheratanga mowhiti. I te mea he kanorau ngā hua tukatuka o ngā wheketere tākai ngāwari, e hiahia tonu ana ngā wheketere tākai ki ngā hua me ngā rauemi PE angiangi, he pumau teitei rānei ngā rahi, i taua wā, he pai ake te pūnaha whakahaere kume porowhita kati. Ahakoa kāore he whakaritenga teitei o ngā wheketere tākai mō ngā hua, ka taea hoki te whiriwhiri i te mea māmā, te pūnaha whakahaere whakatuwheratanga mowhiti.
1. Te hiranga o te whakahaere i te kume i roto i ngā hiato kore-whakarewa
Nā te iti o te taumaha ngota o ngā piripiri kore-whakarewa, tata kore rawa he piri tuatahi, nō reira he mea nui te taurite kume i roto i ngā whakakotahitanga kore-whakarewa. Mā te kore o te ōwehenga kume ka puta ake ēnei raruraru:
(1)I muri i te takai, ka miro te kiri o te roera, ā, ka nui haere te para.
(2) Ko te piko rawa o te kiriata hiato i muri i te whakamaroke ka puta he hapa hanga.
(3) I te wā e hanga ana i ngā pēke, ka miro te taha hiri wera
2. E rua ngā pūnaha whakahaere kume e whakamahia ana i roto i ngā mīhini whakakikorua kore-whakarewa i tēnei wā
Pūnaha whakahaere kume tuwhera: Ka whakauru te pūrua whakauru i te uara kume i whakatakotoria e mātou, ā, ka whakahaerehia e te taputapu te taipana kia rite ki te uara ariā i whakatakotoria e te kaihanga hei whakaoti i te putanga kume.
Pūnaha whakahaere kumetanga porowhita kati: Waihoki, ko te uara kumetanga ka whakatakotoria e mātou ka whakaurua mai i te pito whakauru, ā, ka whakakīia te rango roera mānu ki te hau kōpeke. Ko te kumetanga e pā ana ki te kiriata ko te tapeke o te kaha poutū o te kaha taumaha roera me te kaha poutū o te rango. Ina huri te kumetanga, ka huri te roera mānu, ā, ka kitea e te tohu tūranga te huringa kumetanga, ka tukuna atu ki te pito whakauru, kātahi ka whakatika i te kumetanga.
3. Ngā painga me ngā ngoikoretanga o ngā pūnaha whakahaere kume e rua
(1). Pūnaha whakahaere kume tuwhera
Painga:
Ka tino māmā ake te hoahoa whānui o te taputapu, ā, ka taea hoki te whakawhāiti ake i te rahinga o te taputapu.
Nā te mea he tino māmā te pūnaha kume tuwhera-porowhita, he iti te tūponotanga o te rahunga i te wā e whakamahia ana te taputapu mō te wā roa, ā, he māmā ake hoki te whakatau i te raru.
ngoikoretanga:
Kāore i te tino tika. Nā te whakahaere tika o te taipana, kāore i te tino pai te pumau me te tika i te wā o te huringa hihiri me te pūmau, te whakaterenga me te whakahekenga, me ngā panonitanga o te diameter o te koiri, inā koa ka whakatakotoria te uara kume kia iti, kāore te whakahaere kume i te tino pai.
Te korenga o te whakatikatika aunoa. Ina he rerekē ngā āhuatanga o waho pēnei i ngā rōra kiriata papa, he nui te pānga ki te whakahaere kume.
(2)Pūnaha whakahaere kumekume porowhita kati
Painga:
He teitei te tika i te nuinga o te wā. He iti noa te awe o te huringa hihiri me te huringa pumau, te whakaterenga me te whakahekenga, me ngā panonitanga o te diameter o te koiri ki te whakahaere kume, ā, ahakoa ngā kume iti ake ka taea te whakahaere pai.
